CarPlay - Playlist - Unable to Select song

Hi,

My CarPlay (via Audi MMI) has worked fine for months but recently if I select a song from a playlist, it won’t play and will always revert to the first song of the playlist. I can skip songs ok but as soon as I select a different song, it always then just plays the first song on the playlist. Get the same behaviour for albums.
Any ideas?

Please help.

I didn't find the right solution from the Internet.
